IDENTIFICATION OF CONNECTION TERMINALS
E3/4 , 110V , E1 , E2 : Sensing voltage (110/220/380 Vac)
F+, F- : Connection for alternator field.
3 , E3/4 : Power supply. The power input can be from SHUNT, PMG, and Auxiliary Winding.
S1-S2 : Connection for CT 5A of parallel operation.
S2-S3 : Connection for CT 1A of parallel operation
VR-VR : Connection for potentiometer 1kΩ/1W (It should be isolated using twisted cable for connection)
A+, A- : Analog input voltage. A remote DC voltage to adjust the output voltage of the alternator.
ATTENTION
1. Before connecting the regulator to the alternator , verify in the installation manual, the rated sensing
voltage
2. Incorrect voltage and frequency adjustment can damage AVR.
3. If no potentiometer is used, keep EXT.VR terminal connected. (shorted)
